Hi, I'm looking at being able to set a display colour profile via terminal. I know apps such as SwitchResX are able to change this but i can't figure out how and if it is possible to switch via a terminal command or via a script. This here is what i would like to change. I have googled about and searched through preference files but can't find anything. Any help is much apreciated. Thanks, James

When rendering gradient of luma values you can clearly see that the monitor output from Apple Silicon GPU has lifted/curved blacks (values 0-31 out of 1024 in 10-bit output). Any idea what is going on and how to remediate? It looks like some kind of compensation/calibration for the screen panel response, but it is baked into output regardless of what kind of monitor (or non-monitor) is connected. The same rendering on Intel architecture produces correct linear gradation. We have tried M1, M2, M3 and they all seem to be affected.

When changing icc profile in macOS14.x, app may get 2 "NSApplicationDidChangeScreenParametersNotification". And some platform is normal like M2 Pro Mac mini v14.4.1 will receive once. Any idea about this symptom?

Hello - I’m creating an app that needs to copy ColorSync profiles to the /Library/ColorSync/Profiles directory on macOS and was wondering what is the correct / sanctioned way to write to the /Library directory is? The app won’t be in the App Store. The app needs to run on Big Sur through Sonoma. I spent some time working with ColorSyncProfileInstall() but that seems to want to ask the user permission every single time the function is called - and this app can install up to 25 profiles at a time. (There are actually hundreds of profiles that can be chosen that will come from a server). I’m currently looking at using SMJobBless but that sure seems like using an atomic bomb to swat a mosquito. Any thoughts if SMJobBless is the right way to go? (SMAppService for 13 and on). Thanks!
